The Schwarzschild radius of an object is proportional to the mass. Accordingly, the Sun has a Schwarzschild radius of approximately 3.0 km (1.9 mi), whereas Earth 's is only about 9.0 mm. The observable universe 's mass has a Schwarzschild radius of approximately 13.7 billion light years.
A supermassive black hole thatâs 50 million light years away and is 6 billion times more massive than the Sun. It wasnât easy, though. The radius of the black hole was observed with the Event Horizon Telescope â a chain of radio telescopes in Hawaii, Arizona, and California. By combining these telescopic observations, scientists are able to obtained unprecedented resolutions when observing objects in the night sky.
